CamerasΒΆ

By defining the Cameras node, only patterns which are detected by the given stereo setup will pass the filter. To pass this filter the pattern detection must fulfill the following requirements:

  • The pattern was detected in both images of the stereo camera setup

  • Both detections could be identified as the same pattern, i.e.:

    • Same grid size (Width x Height)

    • Same decoded pattern information when available:

      • Grid spacing

      • Thickness

      • Offsets

    • When UseModel is enabled:

      • Positions of the patterns in left and right image must match under the current stereo model (i.e. their reprojection error in each camera must be smaller than one grid spacing). This allows to distinguish and associate several patterns with identical type in a single stereo camera image pair.

Allowed stereo setups:

  • Single stereo (left + right image)

  • Stereo (left image) to monocular

  • Stereo (left image) to stereo (left image)

Note

The filter is ignored when there are no stereo patterns in the buffer yet.
